Description taken from Hybrid Windows/Mac version of this game

PBS' famous scarlet hound gives pause to teach kids aged four to six vocabulary skills in Clifford: The Big Red Dog -- Phonics. Taking place at a carnival, Clifford and his friends will guide children through 12 activities and carnival games that teach phonics, vocabulary, and spelling skills. Kids will write stories using words and pictures, select the correct letter or sound to fill the high dive pool with water, match correct letters to start the Ferris wheel, decorate a float for the big parade, and much more. Three skill sets are available to adjust to the child's ability, and an automatic help feature will guide young players when they require assistance. A progress report allows parents to monitor their child's advancement. ~ Chris Cavanaugh, All Game Guide
